Abstract

For phase lead compensation ILC, the learning transient and tracking accuracy are determined by learning gain, learnable bandwidth and lead step. The learnable bandwidth is often conservatively selected to accommodate the uncertainties in models, which often degrades the tracking accuracy. In this chapter, the learning transient is analyzed and the tuning of learnable bandwidth and lead step are developed to achieve good learning transient and tracking accuracy simultaneously. Experimental results are presented to verify the tuning process.
